    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 U>F{?PReA?  
    mgQIhXH5L  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: |=K_F3aJ  
    enableservice('AutomationServer', true) O0hu qF$K  
    enableservice('AutomationServer') x({C(Q'O  
    L/Vx~r`P  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 J7+w4q~cB`  
    f.6~x$:)`E  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: )T|L,Lp  
    1. 在FRED脚本编辑界面找到参考. _O]xey^r  
    2. 找到Matlab Automation Server Type Library nwmW.(R4  
    3. 将名字改为MLAPP +TJ EG?o

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 GJA`l8`SQ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: y 1\'( 1  
    1. 创建Matlab服务器。 5h{`<W  
    2. 移动探测面对于前一聚焦面的位置。 DN] v_u+}  
    3. 在探测面追迹光线 xTz%nx  
    4. 在探测面计算照度 |`/TBQz:r  
    5. 使用PutWorkspaceData发送照度数据到Matlab +^|iZbZKx  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Ea $aUORm  
    7. 用Matlab画出照度数据 $ &UZy|9  
    8. 在Matlab计算照度平均值 98XVa\|tl
